This past day I started noticing a weird wiggle or loose vibration coming from the rear when taking off from a stop. It goes till maybe 5-10mph, and it feels like something is squirming around.

The next is a problem I have always seen since I did my transmission swap. If you are going slowly, and in a higher gear, pressing the throttle jerks the car. Press into it, you feel the driveshaft and stuff kinda slap into position, lift off and it kinda does the opposite.

All of the rear bushings are new except the front trailing arm ones which are not worn. Ujoints are all fresh (this winter), and all the connecting pieces like panhard rod and torque rods have poly bushings. The "slap" from the driveshaft, or jerking motion has stayed the same even after swapping out and replacing the horribly worn torque rod bushings. I am not really sure what the heck is causing this. This weekend I was in there and replaced the center mount rubber support, along with the center bearing. No improvement.
